Abstract :
Large starting voltages in metal halide lamps result in sputtering of the electrodes and reduced lamp life. A two-dimensional plasma hydrodynamics model was used to investigate breakdown in metal halide lamp. Images depicting the progress of the breakdown in Ar during cold startup are presented.
